Umm was it plug in all the way. ive thought i was charging my phone in the car and got to my destination and realized that i had not plugged it all the way into the cig lighter. i pull it partially out when im not using it.

Is there another option for charging in the car besides a cigarette lighter? The rental I'm driving has a USB port, but I'm only going to have that for a day or two. When I get my Mini back, I'll be back to just the lighter as a power source.

I'm having the same issue while using the charger that came coupled with the car dock. I've used it in multiple cars and while it does hold a charge longer than it would while not plugged in at all, it's still draining the battery even though the battery icon indicates it's plugged in.

Thats odd. Maybe the car adapter youre using isnt strong enough? I don't know if that makes sense but maybe it just isn't giving enough power to the droid. Or maybe its just defective. I use the car charger that I bought for my enV touch and it works great. I just drove for 5+ hours straight on friday, and 4+ hours on sunday with nav running the whole time with some pandora mixed in at times, and when I unplugged I had full battery. I guess your battery could be whats defective as well
